README

Allows you to use Twig seamlessly in Laravel 4.

Requirements

TwigBridge >=0.6 requires PHP 5.4+ & Laravel 4.1+.

If you need to support PHP 5.3 or Laravel 4.0 checkout out TwigBridge 0.5.*

Installation

Add rcrowe\twigbridge as a requirement to composer.json:

{
    "require": {
        "rcrowe/twigbridge": "0.6.*"
    }
}

Update your packages with composer update or install with composer install.

Once Composer has installed or updated your packages you need to register TwigBridge with Laravel itself. Open up app/config/app.php and find the providers key towards the bottom and add:

'TwigBridge\ServiceProvider'

You can add the TwigBridge Facade, to have easier access to the TwigBridge (or Twig_Environment).

'Twig' => 'TwigBridge\Facade\Twig',

Twig::addExtension('TwigBridge\Extension\Loader\Functions');
Twig::render('mytemplate', $data);

Configuration

TwigBridge's configuration file can be extended by creating app/config/packages/rcrowe/twigbridge/config.php. You can find the default configuration file at vendor/rcrowe/twigbridge/src/config/config.php.

You can quickly publish a configuration file by running the following Artisan command.

$ php artisan config:publish rcrowe/twigbridge

Usage

You call the Twig template like you would any other view:

// Without the file extension
View::make('i_am_twig', [...])

TwigBridge also supports views in other packages:

View::make('pagination::simple')

The above rules continue when extending another Twig template:

{% extend "parent" %}
{% extend "pagination::parent" %}

You can call functions with parameters:

{{ link_to_route('tasks.edit', 'Edit', task.id, {'class': 'btn btn-primary'}) }}

And output variables, escaped by default. Use the raw filter to skip escaping.

{{ some_var }}
{{ html_var | raw }}
{{ long_var | str_limit(50) }}

Extensions

Sometimes you want to extend / add new functions for use in Twig templates. Add to the enabled array in config/extensions.php a list of extensions for Twig to load.

'enabled' => array(
    'TwigBridge\Extensions\Example'
)

TwigBridge supports both a string or a closure as a callback, so for example you might implement the Assetic Twig extension as follows:

'enabled' => [
    function($app) {
        $factory = new Assetic\Factory\AssetFactory($app['path'].'/../some/path/');
        $factory->setDebug(false);
        // etc.....
        return new Assetic\Extension\Twig\AsseticExtension($factory);
    }
]

TwigBridge comes with the following extensions enabled by default:

Twig_Extension_Debug
TwigBridge\Extension\Laravel\Auth
TwigBridge\Extension\Laravel\Config
TwigBridge\Extension\Laravel\Form
TwigBridge\Extension\Laravel\Html
TwigBridge\Extension\Laravel\Input
TwigBridge\Extension\Laravel\Session
TwigBridge\Extension\Laravel\String
TwigBridge\Extension\Laravel\Translator
TwigBridge\Extension\Laravel\Url
TwigBridge\Extension\Loader\Facades
TwigBridge\Extension\Loader\Filters
TwigBridge\Extension\Loader\Functions

To enable '0.5.x' style Facades, enable the Legacy Facades extension:

TwigBridge\Extension\Laravel\Legacy\Facades

FilterLoader and FunctionLoader

These loader extensions exposes Laravel helpers as both Twig functions and filters.

Check out the config/extensions.php file to see a list of defined function / filters. You can also add your own.

FacadeLoader

The FacadeLoader extension allows you to call any facade you have configured in config/extensions.php. This gives your Twig templates integration with any Laravel class as well as any other classes you alias.

To use the Laravel integration (or indeed any aliased class and method), just add your facades to the config and call them like URL.to(link) (instead of URL::to($link))

Functions/Filters/Variables

The following helpers/filters are added by the default Extensions. They are based on the helpers and/or facades, so should be self explaining.

Functions:

asset, action, url, route, secure_url, secure_asset
auth_check, auth_guest, auth_user
config_get, config_has
form_* (All the Form::* methods, snake_cased)
html_* (All the Html::* methods, snake_cased)
input_get, input_old
link_to, link_to_asset, link_to_route, link_to_action
session_has, session_get, csrf_token
str_* (All the Str::* methods, snake_cased)
trans, trans_choice
url_* (All the URL::* methods, snake_cased)

Filters:

camel_case, snake_case, studly_case
str_* (All the Str::* methods, snake_cased)
trans, trans_choice

Global variables:

app: the Illuminate\Foundation\Application object
errors: The $errors MessageBag from the Validator (always available)

Artisan Commands

TwigBridge offers a command for CLI Interaction.

$ php artisan twig:clean
